….	Date: July 29, 2019 01) Robotic contact lens that allows users to zoom in by blinking eyes revealed by scientists “Device mimics natural electric signals in human eyeball … The lens is made from polymers that expand when electric current is applied. It is controlled using five electrodes surrounding the eye which act like muscles. When the polymer becomes more convex the lens effectively zooms in. “The system developed in the current study has the potential to be used in visual prostheses, adjustable glasses, and remotely operated robotics in the future,” researchers wrote in the paper published in Advanced Functional“	….
